I succeeded in capturing them, and you may imagine my delight when 
I found that one of them carried a pollinium of Disa uniflora on one of 
its legs. 
Mr. Trimen states, in his work on ‘South African Butterflies,’ that 
Meneris Tulbaghia—that is the name of this pretty insect—shows a 
special liking for bright red flowers, and that he observed it on Nerina, 
Hemanthus, Antholyza and Disa ferruginea,* Sw. 
As Disa uniflora is the only other red flower occurring on the moun- 
tain at this season, and as its gorgeous colour and deeply hidden 
nectar indicate a day-flying insect with a long proboscis, one should 
almost expect that Meneris, which is the only large butterfly on the 
mountain, and pretty common at the altitude where the Disa grows, 
should have something to do with its fertilization. 
This suspicion is confirmed by the occurrence of the pollinium on a 
leg of the specimen of Meneris exhibited, and by a note which I received 
this evening. Mr. 8S. B. Morgenrvod writes: ‘ One day, when I entered 
a gully with a bunch of Disas in my hand, a large number of butterflies 
(Meneris) were attracted by the flowers, and even settled on them.’ 
I fully agree with Mr. Bolus in considering D. uniflora as a plant 
which at present is chiefly propagated by vegetative means, but it is 
also interesting to know that the sexual reproduction, although not the 
rule, still exists. 
Additional Notes read March 27, 1895. 
By the courtesy of the Conservator of Forests, I was allowed to 
examine the Disas in the Forest Reserve on Table Mountain, which | 
did two days after the last meeting. There were 228 flowers open, 
which I found in the following state : . 
Stems | stigma | 
pollinated, | Pollinated. 
Both pollinia present a Ne 205 2 | 
One pollinium removed ae = 10 5 
Both pollinia removed of ae 2 4 | 
which shows that twenty-three had been visited by insects, equal to 10 
per cent., and 11 fertilized, representing 5 per cent. ; but as most of these 
flowers were fresh enough to last another week or fortnight, some more 
fertilization will probably have taken place since. 
. * Mr. Trimen says Disa cornuta, but I suppose he means D. ferruginea, Sw., as 
the former is different in colour, and not in flower when Meneris is out.
